Ultrasound is commonly used in medicine for imaging diﬀerent organ systems. Also, it is widely used to monitor fetal development. The most common ultrasound imaging technique is B-mode, which uses an array of transducers to generate a narrow beam.
The array with dynamic focusing is implemented by phase shifters which are complex and costly. Also, the beamwidth is not suﬃciently narrow which means it cannot provide high resolution. My research will investigate a new method which doesn’t need narrow beam and can be implemented by only one transducer. The new system can give potentially higher resolution and signiﬁcantly reduce the cost compared to conventional B-mode ultrasound imagers.
